TOKYO, November 14. /TASS/. The repair operations at Japan’s crippled Fukushima Daiichi nuclear power plant that were aimed at preventing radioactive water discharges into the ocean have yielded no result, the NPP operator Tokyo Electric Power Co (TEPCO) reported on Friday.
The water used for cooling the damaged reactors at the plant that was damaged by a powerful tsunami wave triggered by an earthquake in March 2011 is still leaking into the NPP drainage system even after last week’s operations to stop the leak.
According to previous reports, due to the major damage of the plant’s infrastructure most of the water that is poured inside the damaged reactors for their cooling later leaks into the drainage system and gets into the ground waters and then into the Pacific Ocean. According to specialists, the volume of contaminated liquid that is leaking into the ocean is increasing by 400 tons daily. The radioactive contamination level in the ground waters, according to TEPCO, is very high — the content of cesium isotope in them reached 267 Becquerel per 1 liter of water, while the established norm of its content in the water discharged into the ocean is 30 Becquerel.
TEPCO specialists since April to early November this year conducted the work to stop the leakage of highly radioactive water into the Fukushima Daiichi NPP drainage system from where it leaks into the ocean through ground waters.
